Let’s face it, users are impatient. They demand a blazingly fast experience and accept no substitutes. While the effects of poor performance are obvious, it makes one wonder about the relationship between client latency and the “perception of speed”. After all, the user can trigger many state change events (page load, submit a form, interact with a visualization, etc.) and all these events have an associated latency to the client. However, are certain types of latency more noticeable to the user then others?

Performance for end users is the metric by which most businesses judge their web applications’ performance: is the responsiveness of the application an asset or a liability to the business? Studies show that users are growing more and more demanding, while average page-loads are getting bigger and bigger. Combine that with frequent releases and cross-business updates, and pretty soon the optimization job is never quite done.

Capability breeds dependence. The more you can do, the more is asked of you. The more time you save, the more time you spend seeking out ways to save more time or money. If less really is more, how do you do more with less? Effective system monitoring could help you break free of the system shackles and use your System i (iSeries) network to save time and money.

Is a lack of availability costing your business thousands or even hundreds of thousands of dollars? Assessing the true financial impact of unplanned downtime may surprise you. Placing a dollar amount on this issue is often the first step and biggest motivator to meeting your ongoing availability requirements.

Many IT Managers will be familiar with the ‘disk or die’ ultimatums that a disgruntled system can issue. If the system demands feeding and threatens to shut down if it doesn’t get more disk to chew, it’s time to address the issue of disk once and for all. The expense of using disk to accommodate problems in the hope of buying extra investigation time is a quick fix that few organizations can sustain.

Imagine you had a friend that turned up right before something bad was going to happen and told you how to avoid it. Like if you don't attend to that looping job silently going about its business, the system in India will fall over and the downtime will cost the company hundreds of thousands of dollars in idle work hours. Yes, a friendly forewarning wouldn't be bad. We would suggest employing a job monitor – it's your friend on the inside.

IT Managers are not in the business of luck. They need to prepare for every disaster scenario, every contingency and ensure that even when every object, job and process is running 100% perfectly on the system, some other unforeseen network element doesn't swoop in and ruin all their efforts, just because it resides outside the parameters of the System i. After all, in a situation like this, people remember the one thing that went wrong – not the millions of things that went right – it's unfortunate, but that's life.

Every popular email client will display HTML content sent in email. However, not every email client has a "web standards" compliant HTML rendering engine. Therefore, the same email may render differently across different email clients. This whitepaper offers practical solutions to help designers, coders, and non-designers alike build a successful email that will render well across all email platforms.

Using digital control in power supplies is considerably more flexible than analog control in its ability to adapt to changes and digital control inside the power supply results in advantages to the system application such as improved efficiency, fewer external components and reduced overall cost.
